* ad7150
   - sense of bit for controlling adaptive vs fixed threshold was flipped.
 * adt7316
   - Fix a build issue due to wrong headers for gpio usage.
 * lsm6dsx
   - correctly suspend / resume i2c slaves when the host goes to sleep.
 * mlx90632
   - relax a compatability check to allow for newer devices.
 
 Also one counters fix
 
 * counter/ftm-quaddec
   - missing dependencies in Kconfig.
